PS: I'd love some sorting/filtering options: sort by location, filter out certain locations (like my main storage place, to see if I have some orphaned resources). I usually do it in excell, but, yes, it would be nice.

Well, I do copy and paste, and because I don't fancy it, I suggested this. Your stores must be as crammed as mine, or even more, and at least on my pc, whenever I make a paste operation of that size in excel, it hangs for a while.
